WATER CUT-OFF.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed December 28,1905. $611311 110- 293,555-

To aZZ whom, it may concern.-

Be it known that I, GEORGE HENKEL, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in- Water Cut-Offs, of

which the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to water cut-offs, and is in the general natureof an improvement uponwhat is set forth in United States Letters PatentN 0. 470,489, granted to me lviiarch 8, 1892, for improvements inwaterouto" s.

The general object of the invention is to provide an automatic device,for use more particularly in connection with the discharge spout of aroof,zwhich, will direct the first flow of water from the roof during arain, which flow is usually polluted with dirt and other washings fromthe roof and is therefore not desirable, to a suitable waste discharge,said device subsequently changing the direction of the flow when thewater has become clear and directing the same to a suitable storagereceptacle, such as a cistern.

More specifically, my present invention has for its object to provide asimple, compact,

inexpensive and eflicient mechanism by which these results may beobtained, and by which the amount of automatic waste dis charge may bereadily regulated, while the automatic feature may be renderedinoperative at will, making the waste discharge permanent until theautomatic action is again desired.

To these and other ends my present invention consists in certain novelfeatures which I will now proceed to describe, and will thenparticularly point out in the claims.

In the accompanying drawings, Figure 1 is a s1 de elevation ofastructureembodying 1nvent1on in one form; Fig. 2 1s a plan view of ,thesame; Fig. 3 is a central vertical sectional view, taken on the line :0a: of Fig. 2 and looking in the directionof the arrows; Fig. 4 is acentral vertical sectional view, taken on the line y y of Fig. 1 andlooking in the direction of the arrows; Fig. 5 is an enlarged detailsectional view, taken on the line 2 z of Fig. 4 and looking in thedirection of the arrows; Fig. 6 is a diagrammatic view illustratingadifferent position of the parts from that shown in the precedingfigures; Fig. 7 is a similar view,

showing the parts adjusted for permanent discharge to waste; and Fig. 8is a plan view of I a portion of what is shown in Fig. 7.

In the said drawings, 1 indicates a suitable casing or housing, intowhich enters at the top a conduit 2, preferably in the form of a collaradapted to be connected to the discharge pipe of the roofof thebuilding. The casing 1 is provided with or has connected to its lowerportion a waste conduit 3 on one side of the central plane thereof and astorage conduit 4 on the opposite side, said conduits being preferablyalso in the form of collars Y adapted to receivepipes leadingrespectively tothe waste discharge and to the cistern or other storagereceptacle provided for water to be stored. Within the main housing 1there is located a casing 5, preferably cylindrical in form, dividingthe lower portion of the casing into two parts, communicatingrespectively with the waste outlet 3 and storage outlet 4. The casing 5has at its top an inlet opening 6, while its lower portion is providedwith an outlet opening 7, discharging toward the waste outlet or conduit3. ithin the casing 5 there is located a water wheel '8, mounted on ashaft 9, and preferably constructed in substantially the same'manner asthe water wheel of my prior Letters Patent hereinbefore referred to, thebuckets being of such a character as to receive the water which entersthrough the opening 6 and retain the same so that the weight thereofwill cause the wheel and its shaft to revolve, the water beingdischarged through the opening 7. Between'the discharge mouth of theentering conduit 2 and the top of the casing 5 there is. located adeflector, consisting of a deflecting plate 10 having at its lateralmargins upwardly extending flanges 11, by means of which the deflectoris pivoted to the housing 1 through pivots 12 and 13. The pivot 12-isextended outside of the housing 1 and bent at an angle to form a detentarm 14, lying outside of the housing. A suitable weight is provided tomove the deflecting plate, when free, to a position such as to cause itto discharge toward the storage outlet or conduit, as illustrated inFig. 6.. I prefer to attach this weight directly to one of thetransverse margins of the deflecting plate, as shown at 15, therebyrendering the structure more compact and concealing and inclosing theWeight within the housing. The deflecting plate 10 is further providedwith an aperture 16, through which a portion of the water which isdischarged from the con- ITO duit 2 into the deflecting plateis-permitted to pass to the inlet opening 6 of the inner casing 5 whenthe parts are in the position shown in Figs. 1 to 4, inclusive. In orderto prevent too large a portion of the water from being thus diverted, Iprovide the deflector with an induction conduit 17, having a restrictedreceiving mouth 18. This conduit is preferably constructed in the mannershown, of a single sheet of metal bent to form two substantiallyparallel triangular sides, closed along one pair of their margins by thebody of the metal itself, and along another pair of their margins by thedeflecting plate 10, the opening 16 being located in this side, whilethe margins which are uppermost when the parts are in the position shownin Figs. 1 to' 4 are separated so as to form a relatively narrow slotwhich forms the constricted receiving mouth 18, as shown moreparticularly in Fig. 2.

The shaft 9 projects through the housing 1. at one end and isthere'provided with a pinion 19, the same being preferably in the formof a disk secured to the projecting end of the shaft and havingtwo pins20 extending outward from its front face. These pins mesh with the teethof a gear 21, mounted on a shaft 22, and any suitable provision may bemade for causing the shaft and gear to rotate in unison, but I preferthe construction shown, in which the gear is loosely mounted on theshaft, the latter having an arm 23 mounted thereon, said arm having atits extremity a projection or finger 24,

which engages an aperture 25 in the disk.

The arm 23 is threaded to fit upon a threaded sleeve 23, splined orotherwise rigidly secured to the shaft 22 terminating in a stop orcollar 23, against which the arm bears when the gear and arm rotate inunison. These parts are preferably supported in the manner shown, inwhich 26 indicates a base in the form of a bar secured to the outer faceof the housing 1 on the front thereof and having an apertured lug 27 atits lower end. This bar has a bearing 28 for one end of the shaft 22 anda bearing 29 for one end of the shaft 9. A cover 30 incloses andprotects this gearing, being connected to the base 26 by means of a lugor projection 31 at its lower end, fitting in the aperture of the lug 27of the base, while the upper end of the cap or cover is provided with anapertured lug 32, through which passes a screw 33, which is threadedinto the upper end of the base bar 26. The end of the shaft 22 which hasits bearing at 28 is removable or separable from the bearing at thatpoint, so that the said shaft, with the gear 21 and arm 23, is removablealong with the cap or cover 30. The shaft 22 has a bearing in the cap orcover at 34, and extends outward beyond the cap or cover at that point.

The projecting extremity. of the shaft 22 has attached to or formedthereon, preferably by bending the shaft at an angle, a trip 'arm 35. 36indicates a trip lever, pivoted on the outer face of the casing betweenits ends, as indicated at 37. tremities bent to extend outward at anangle to the body portion thereof, said extremities being indicatedrespectively by the numerals 38 and 39. It will be observed that theextremity or arm 38 is shorter than the extremity or arm 39, for thepurposes hereinafter set forth.

In the ordinary or normal operation of the parts, they are first set tothe position shown in Figs. 1 to 4, inclusive. In other words, thedetent arm 14 is depressed and engaged by the shorter arm 38 of the triplever 36, and in this position of the parts the longer arm 39 of saidtrip lever lies in the path of the tripping arm 35. This latter is shownin the drawings as being in a position such that it is just about toactuate the trip lever, but, when the apparatus is first set to operate,said trip arm will lie upon the other side of the arm 39. Assuming thata rain occurs, and that water from the roof enters the apparatus throughthe conduit 2, this first discharge of water, being undesirable, will bedeflected by the plate 10 in such a way as to be discharged through thewaste conduit 3. A small portion of this water will, however, enterthrough the restricted mouth 18 of the conduit 7, and will be dischargedthrough the aperture 16, falling through the inlet opening 6 of thewater wheel casing, and successively flllingthe buckets of the waterwheel as the latter rotates. Excessive speed of the water wheel isprevented, however, by the restricted conduit which supplies the same.As the water wheel shaft 9 rotates along with the water wheel, thepinion 19 imparts a slow movement of rotation to the gear 21, andthrough this slow train to the shaft 22,,which latter carries thetripping arm slowly around until it comes into contact with the arm 39of the trip lever. As the water wheel continues to rotate, the trippingarm moves the trip lever until the shorter arm 38 thereof releases thedetent arm 14 of the deflector, whereupon the weight 15 swings thedeflector over into the position shown in Fig. 6, thereby diverting theflow of water to the storage conduit 4. The relations of the parts aresuch that this shifting of the deflector does not occur until ample timehas been allowed for the polluted water, which is first discharged, tobe carried off through the waste outlet. It will also be noted thatowing to the triangular shape of the conduit 7, with the parts in theposition shown in Fig. 3, the mouth of the conduit is directed towardthe incoming flow of water, so that a portion thereof is diverted to thewater wheel, while the change of position of the deflector to that shownin Fig. 6 turns the closed portion of This trip lever has its exsaidconduit toward the incoming water and the mouth away from it, so that nowater enters said conduit, and the supply to the water nently dischargeto waste.

wheel is cut off. After the discharge has ceased, the apparatus may bereset in an o-bvious manner.

If the cistern or storage receptacle is full, or if, during a certainperiod, such as the winter season, it is not desired to store any of thewater, the automatic operation of the apparatus may readily beprevented, the deflector being located in a position such as to perma-It is for this reason that the arms 38 and 39 of the trip lever 36 aremade of different lengths. Upon referring to Figs. 7 and 8 it will beseen that the trip lever may be so turned as to engage its longer arm 39with the detent arm 14, in which position of said lever the arm 38 isnearest to the trip arm 35. But said arm 38 is too short to be engagedby said trip arm, which sweeps over it without touching it, so that thewater wheel may revolve indefinitely without operating the trip arm andshifting the deflector.

The screw threaded connection between the arm 23 and shaft 22 providesa. simple and effective means for adjusting or regulating the quantityof the preliminary waste discharge. If the machine is set, as shown,with the arm 23 screwed up against the collar 23*, then the shaft 22rotates in unison with the gear 21 as soon as the water wheel starts,and the tripping arm begins at once to, travel around toward the triplever. If a longer period of waste discharge is desired, all that isnecessary is to move the arm 23 outward along the threaded sleeve 23away fromthe collar 23*, and this may be readily effected by simplyturning the tripping arm 35 in a direction such as to cause the shaft 22to rotate in its normal direction of rotation, but independently of thegear 21. This may be read ily effected for the reason that the said gearis loosely mounted on the shaft, and the frictional resistance of thewater wheel and its shaft geared thereto is sufficient to hold the arm23 against rotation, permitting the shaft 22 to turn therein. As theshaft 22 rotates while the arm 23 is held against rotation, the said armis moved outward along the sleeve 23, with which it is in threadedengagement, moving away from the collar 23 but maintaining itsconnection with the gear 21 by reason of the engagement with theaperture 25 in said gear of the projection or finger 24. The arm 23 isthus moved-outward or .forward on its shaft a greater or less distance,according to the greater or less increase in waste discharge desired.The apparatus then being set in the manner hereinbefore de' scribed,when the water wheel begins'to rot ate, the initial period of rotationin unison therewith of the gear 21 turns the arm 23 upon the shaft 22,screwing it backward thereon until the arm comes into contact with thecollar 23*, and during this period the tripping arm remains stationary.After the arm 23 engages the collar 23 the tripping arm rotates with theshaft 22 and finally actuates the trip lever to release the deflector: Amore or less extended period of rotation of the water wheel is thusprovided, during which the tripping arm is not traveling toward the triplever, and the time intervening between the starting of the water wheeland the tripping of the deflector is thereby correspondingly increased.In case the shaft 22 should tend to turn with the gear 21 and arm 23before the said arm is in contact with the collar 23 such rotation canonly continue until the tripping arm comes into contact with the triplever, whereupon said tripping arm and its shaft will be held stationaryby the resistance of the trip lever until the arm23 engages the collar23 and the shaft 22 is positively turned to cause the tripping arm toovercome the resistance of the trip lever. In either case the trip leverwill not be actuated until the predetermined time. It will thus be seenthat provision is made for regulating the amount of water discharged towaste, such regulation being readily effected.

It will be observed that the structure is compact, and that the waterwheel and gearing are so inclosed as to be effectually protected, thegearing being inclosed in a sepa rate cover which isreadily removable togive access to the same for inspection or repair. It will also beobserved that the worm and worm wheel employed in the structure shown inmy former patent are dispensed with, and a form of gearing substitutedtherefor which is much less expensive in construction and simpler inoperation, and which permits a parallel arrangement of the shafts andpivotal axes of the moving parts, thereby further increasing thecompactness of the structure.
